Conservation experts warn Ahmedabad, one of the world's most polluted cities, faces a mammoth task defending its newly won UNESCO status as its fragile cultural icons decay under neglect, traffic and trash
Ahmedabad's conservation committee has three years to document close to 3,000 buildings of heritage value to strict UNESCO standards -- a monumental task for Ghosh's small team.
UNESCO could revoke or downgrade Ahmedabad's listing to "heritage in danger" should the deadline be missed and the committee fail to show it has slowed the decline and destruction of the old city.
Jigna Desai, associate professor at CEPT University's architecture faculty in Ahmedabad, said the coveted UNESCO inscription would mean little if there was nothing left to protect.
"How do you make sure that this evidence does not deteriorate, that the evidence stays for the world to see, or the next generations to see?" she told AFP.
Ghosh's deputy at the heritage council, P.K.V Nair, agrees: "Getting the listing was one thing, now meeting that challenge is more important."
